This booklet is intended to be used as a ready reference to typ-ical standard, miniature and subminiature cylindrical connectorpart numbers and terminology. Reading its brief pages will notmake you a connector expert, but should guide you in becomingfamiliar with the product, in order to better serve our customers.

Note: Many of the connector products in this brochure were for-merly known as “Bendix” products. These products are nowmanufactured and sold under the Amphenol ® brand name. Thename “Amphenol” will replace the name “Bendix” on productsand literature in the future.

Amphenol Aerospace is a Certified ISO 9001Manufacturer.

Heavy Duty Cylindrical Connectors

• Class L - for the heaviest loads
– Current range 40 to 200 amperes– Direct current or single/three phase, 60/400 Hertz
alternating current– Automatic grounding for safety

• QWLD - for most power and control circuits– Military qualified connectors and commercial

equivalents available– Increased shell size for greater durability than similar stan-

dard connectors

• Class L and QWLD have 5 key/keyway shell polarization and double stub thread coupling

• QWL – a more economical, compact heavy duty design for commercial power and control applications; single key shell polarization and double stub thread coupling
